cnty per cent to Maria D. 0., Honduras Application March 18, 1947, Serial No. 735,518

3 Claims.

My invention relates to improvements in fountain combs for applying hair oils, or hair tonics, to the scalp, the primary object in view being to provide a simply constructed device of the character indicated which is especially adapted for manipulation over the scalp and for easy operation, all by one hand, hair tonic, under pressure on waste and without irritating the scalp.

To the accomplishment of the above, and anappearing, a preferred embodiment of my invention has been illustrated in the accompanying drawing, set forth in detail in the succeeding description, and defined in the claims appended hereto..

In said drawing Figure 1 is a view in longitudinal section of my improved fountain comb in the preferred embodiment thereof and with parts shown in side elevation,

Figure 2 is a view in end elevation of one of the teeth drawn to a larger scale,

Figure 3 is a fragmentary view in longitudinal section taken on the line 3--3 of Figure 1 and drawn to a larger scale to better illustrate the details of the valve member and associated parts.

Figure 4 is a similar View showing the valve member unseated,

Figure 5 is a view in perspective of the ejector,

Figure 6 is a detail view in transverse section' taken on the line 6-6 of Figure 3 and drawn to a further enlarged scale.

Figure 7 is a view in'transverse section taken on the line 'l'| of Figure 1.

Referring to the drawing by numerals, in the illustrated embodiment thereof, my improved fountain comb comprises an elongated handle I which is hollow to provide therein an axial liquid containing pressure chamber 2 extending from end to end of said handle, and which is prefer?- ably circulartransversely with a tapered front end 3 at the front end of said handle. The handle I is of undulating form, longitudinally, and externally, as indicated at 4, to provide for obtaining a firm hand grip thereon, and is provided with a longitudinal, top, external guide groove 5 for a purpose presently seen. A closure cap 6 is threaded onto the rear end of the handle I to close the rear end of the chamber 2 and has formed therein an axial small bore I, the function of which will presently appear.

A manually operable ejector is provided for forcing liquid out of the chamber 2, under pressure, and which comprises a substantially U-shaped, rod-like member 8 having one leg 9 to eject hair oil, or to the scalp without slidably extended through the bore 1 into the chamber 2 and provided with a forwardly tapering piston 10 threaded thereon, as at H, and adapted to fit into the tapered front end 3 of said chamber 2 to close said front end. The other leg l2 of said member 8 is. adapted to extend. alongside the top of the handle I and is provided with a terminal, lateral, guide lug l3 thereon slidably fitted in the groove 5 to prevent said member 8 from turning with respect to the handle l. A terminal, concave, thumb-gripped seat I4 is provided in said leg l2 on the side thereof opposite the lug 13.

At the front end of the handle I is a comb section 15 comprising a substantially tubular comb back l6 having an axial through, manifold bore H smaller than the front end 3 of the chamber 2, a reduced front end nipple l8, co-planar, radial, bottom discharge bores l9 leading from said manifold bore I! with enlarged outer end sockets 20, and a reduced rear end 2| threaded into the front end of the handle I to detachably attach said comb back I6 and hence the comb section 15 to said handle I with said comb back l6 extending endwise from said handle in axial alignment therewith. A screw plug 22 closes the outer end of the nipple l8.

pA battery of hollow teeth 23, which are cylin-' drical with round tapered outer ends 24 are threaded at inner ends thereof into the sockets 20. -The'teeth 23 are graduated in length so that the outer ends 24 thereof describe an arc whereby said ends are adapted to fit against a scalp represented at S. The teeth 23 form bores 26 therein with tapered outer end valve seats 21, and the outer ends 24 of said teeth are with reduced axial discharged ducts therein leading from said seats 21.

Disk-like valve members 28 are slidably fitted in the bores 26 of the teeth 23 with beveled bottoms 29 adapting said members to seat on the seats 21 and said members 28 are provided with axial stems 30 slidably fitted in the discharge ducts 25 and provided with rounded outer ends 3| extending for a slight distance out of the discharge ducts 25 when the valve members 28 are seated. Coil springs 32 in the bores 26 yieldingly seat said valve members 28. Circumferentially spaced cross grooves 33 in the valve members 28 provide for liquid passing said members, and longitudinal grooves 34 in the stems 30 provide for liquid discharging along said stems out of the discharge ducts 25. Radial face grooves 35 in the outer ends 24 of the teeth 23, at the outer ends of the discharge ducts 2,5, prevent said ducts provided 25 from being closed by a scalp against which the outer ends of said teeth are pressed.

The manner in which the described fountain comb is designed to be used and operated will now be described.

The chamber 2, bore l1 and teeth 23 are filled with liquid, hair oil, or hair tonic, not shown, preferably by removing the screw plug 22, inserting the nipple l8 into the liquid, and pulling the piston it rearwardly from the front end 3 of the chamber 2 by pulling on the U-shaped member 8 with one hand, while the handle I is grasped by the other hand. After the filling operation, the screw plug 22 is, of course, replaced to close the nipple !8. With the handle I grasped by one hand, the teeth 23 are engaged with and moved over the scalp S with pressure exerted toward the scalp to force the valve stems 30 inwardly of the discharge ducts 25 to thereby unseat the valve members 23 and thus open the discharge ducts 25. While the teeth 23 are being moved, as described, the member 8 may be moved forwardly by the thumb of the hand seated in the thumb grip seat It, as shown in dotted lines in Figure 1, and to thereby force the piston Ht forwardly. Such movement of the piston I'll will, obviously, force the liquid out of the teeth 23 onto the scalp S, by way of the grooves 33 in the valve members 28, the grooves 34 in the stems 3B, and the discharge ducts 25. As will beseen, when the piston H3 is moved forwardly into the front end 3 of the chamber 2, said piston closes said end of said chamber and has reached its forward limit of movement with liquid still remaining in the bore l1 and teeth 23. This liquid may be discharged by repeat forward movement of the member 8 so that the comb section 95 may beemptied, if desired, before refilling of the device.

By varying the pressure exerted against the scalp S by the teeth 23, from the teeth 23 may be varied as desired.

The foregoing will, it is believed, sufiice to impart a clear understanding of my invention, without further explanation.

Manifestly, the invention, as described, is susceptible of modifications, without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claims.

What I claim is:

1. In a fountain comb, a hollow handle forming a liquid containing chamber therein, a comb section extending from said handle and including a comb back having a manifold bore therein communicatingv with said chamber, said back being provided with hollow teeth communicating with said bore, an ejector operative in said chamber from outside the same to force liquid out of said chamber, bore and teeth, and normally closed valve means in aid teeth having stems rojecting the quantity discharge out of said teeth, said valve means being operative to open the same by pressure exerted against said stems, said ejector comprising a U-shaped manipulative member having a leg endwise movable in said chamber with a piston thereon, said member having another leg extending alongside said handle with a thumb grip seat therein for seating the thumb of a hand grasping said handle, whereby said member may be manipulated by the thumb of said hand.

2. In a fountain comb, a hollow handle forming a liquid containing chamber therein, a comb section extending from said handle and including a comb back having a manifold bore therein communicating with said chamber to receive liquid therefrom, said back being provided with hollow teeth communicating with said bore to discharge liquid from said bore, and an ejector operative in said chamber from outside the same to force liquid out of the chamber into the bore, said ejector comprising a U-shaped manipulative member having a leg endwise movable in the chamber witha'piston thereon, said member having another leg extending alongside said handle with a thumb grip thereon for seating the thumb of a hand grasping the handle whereby said member maybe manipulated by the thumb of said hand.

3. In a fountain comb, a hollow handle forming a liquid containing chamber therein, a comb se-ction extending from said handle and including a comb.- back having a manifold bore therein com-- municating with said chamber to receive liquid therefrom, said back being provided with hollow teeth communicating with. said bore to discharge liquid from said bore, and an-eiector operative in said chamber fromoutside the same to force liquid out of the chamber into'the bore, said ejector comprising a U-shaped manipulative member having a leg endwise movable in the chamber with a piston thereon, said member having another leg extending alongside said handle with a thumb grip thereon for seating the thumb of a. hand grasping the handle whereby said member may be manipulated by the thumb of said hand, said handle having a longitudinal groove therein and the second mentioned leg being'provided with a guide member slidable in said groove to prevent said member from turning with respect to said handle.
